What is the scientific name of the New World Screwworm?

The New World Screwworm is scientifically known as Cochliomyia hominivorax. This species is a parasitic fly that primarily affects mammals, including livestock and humans, by laying its eggs in open wounds. Once hatched, the larvae feed on living tissue, which can lead to significant health issues, economic losses in agriculture, and even fatalities in severe cases.

Cochliomyia hominivorax is particularly noteworthy due to its impact on livestock health and the livestock industry, as outbreaks can devastate herds. The correct identification of this species is crucial for effective pest control and management strategies in veterinary practice and public health.

The other options listed represent different types of flies that do not have the same implications as Cochliomyia hominivorax. For instance, Stomoxys calcitrans, commonly known as the stable fly, is not a screwworm and primarily feeds on blood. Musca autumnalis, known as the face fly, also does not exhibit the parasitic behavior characteristic of the screwworm. Haematobia irritans, or the horn fly, is another blood-feeding fly that affects cattle but is not associated with the tissue damage seen with screwworm infestations.
